High Dimensional Accuracy
Phenolic Molding Compound SiON®
We Continue Challenge for Realization of
"Non-machining process" which has been Hoped
for Long Time.
Advantage
- Excellent dimensional accuracy in continuous molding process
- Low dimensional change in environment for use
- Low CTE
- Low anisotropy
- Collarless is possible by high creep resistant
